I just bought a pair of $50 Koss TBSE (like Koss DJ100/200) and I am really surprised at how much I like them. I am considering buying a better set of headphones ($200-300 if necessary) and would like to get some that have similar sound to the Koss but somewhat better with more detail and possibly speedier response...hard to explain but like balanced armature IEMs.
I really like the forward and engaging mids (stolen from tdockweiler description) of the DJ100 and I really like the bass but I don't know how to describe it. I don't believe they're basshead phones but I like the bass that I'm hearing.
Any recommendations would be appreciated.
